Abstract
In an article in the Journal of Diabetes Science and Technology, Laffell et al examined the accuracy and performance of a seventh-generation "G7" continuous glucose monitor (CGM) system in participants with type 1 diabetes aged 2 to 17 years. The study had notable points which increase the generalizability of the authors' findings to usual clinical practice, such as accuracy assessment across a wide range of glycemia in the arm and abdominal area, at variable rates of change and time periods (beginning and end of sensor wear). However, accuracy measurements in the younger cohort (2-6 years old) were relatively few. Overall and per-sensor accuracy assessments using standard accuracy metrics were consistently high. The authors also highlighted the enhanced features of the G7 system compared to earlier generation systems, which support better usability.
